o
Equalization – The first switch selects the equalization group (G1 or G2). The center
“off” position selects the RIAA playback equalization for that input. The second switch
selects either EQ1 or EQ2 within the selected group and is inactive if RIAA is selected.
(See
Section 4.4
for details of the other equalization curves)
o
The load adjustment buttons may be used instead of using the remote control to adjust
the actual cartridge loading; however, the internal memory
ONLY
stores the loading
value for each input when selected using the buttons shown here in the Center-lower
Section. The stored loading value will be applied whenever that input is selected. (See
Section 3.4
for more detail.) When using a MM cartridge, the input capacitance of the
Phono III
(120pF) is automatically added to any selected value. Thus, the minimum
capacitance shown on the LED display for a MM cartridge will be 120pF.
o
A small opening labelled “Reset” clears the loading memory for the selected input
without using the buttons or remote. The LED display will then show either “0 ohm” or
“120pF”. (Use the provided 0.050” hex key wrench for this purpose instead of a
paperclip.)
Notes:
(1)
When powered on it takes approximately 30 sec for the main amplifier power supplies to reach
operating voltage and stabilize. During this time the Standby LED will show a red-orange color and
will blink at a 1Hz rate.
(If the Standby LED shows a red or green color only, turn off the unit and
contact DSA.)
(2)
An input selection cannot be made, nor can the
Phono III
be switched to the Mute or Run mode,
until after the power supplies have stabilized which will be indicated when the standby LED stops
blinking.
(3)
When switching between the Standby and the Mute mode, there is a delay of a few seconds for the
Phono III
to come out of the Standby mode, and before the Mute LED will illuminate. This is due to a
startup delay in the output stage for each channel.
(4)
Once in the Mute mode, switching between the Mute and Run modes is instantaneous, as is the
response when switching from Run to Mute.
